What instrument measures emotions?

Answer 1

The frequency of sound is measured by a frequency meter. The volume is measured using a decibel meter

Sound Level Meter

The sound level meter is the basic measuring instrument for noise exposures. It consists of a microphone, a frequency selective amplifier, and an indicator. At a minimum, it measures sound level in dB SPL. An integrating function may be included to automate the calculation of the TWA or the noise dose.
Sound is measured with a sound-level meter or a VU meter. A sound-level meter measures the loudness of sound in decibels (dB) units, and a VU meter measures it in volume units (VU).

One of the most common instruments used to measure sound is the decibel meter.

Answer 2

There isn't a single instrument that measures emotions, as emotions are complex and subjective experiences. However, tools like surveys, physiological measures (such as heart rate or brain activity), and behavioral observations can be used to assess aspects of emotion. It often takes multiple measures to gain a comprehensive understanding of someone's emotional state.

Answer 3

The instuments that measure pressure are hydrostatic and aneroid. A barometer, manometer, and tire gauge all measure pressure. Bordon gauges are industrial instruments that measure pressure.
Guage, Barometer
manometer

Commonly called a tire pressure gauge.
A measurement of pressure is PSI (pounds per square inch). There are gages that measure PSI.

The answer depends on what you are asking about:

For measuring blood pressure you could use a manometer.

For measuring tire pressure you could use a tire pressure guage.

For measuring air pressure you could use a barometer.

For measuring electrical pressure (also known as potential difference) you could use a voltmeter.

Note

There are lots of other things which may need to have their pressure measured, so when you ask a question about pressure, please say exactly which pressure you mean.
